A disjunction is a compound statement formed by joining two statements with the connector OR. The disjunction "p or q" is symbolized by p q. A disjunction is false if and only if both statements are false; otherwise it is true. The truth values of p q are listed in the truth table below.
Grace weighed 167 pounds before she started her exercise program.
Step-by-step explanation:
Given,
Weight lost by Grace = 45 pounds
Weight of Grace after exercise weeks = 122 pounds
Let,
x represents the weight of Grace before she started the exercise program.
Loss means subtraction, therefore,
We will subtract the lost weight from original weight.
Original weight - Weight lost = Weight after exercise weeks

Adding 45 on both sides

Grace weighed 167 pounds before she started her exercise program.

Answer:
C
Step-by-step explanation:
Any value of x makes the equation true.
Answer:
Step-by-step explanation:
z varies inversely
so z=a/x^2
9=a/(2/3)^2
9=a/(4/9)
9=9a/4
a=4
z=4/x^2
z=4/(5/4)^2
z=4/(25/16)
z=64/25
The only correct answer would be D, all you do it plug in the x and y values, such as (0,5)
A) 5 = (0 + 11) - 5
5 = 11 - 5
5 = 6
B) 5 = 11(0) - 5
5 = 6
C) 0 = 11(5) + 5
0 = 55 + 5
0 = 60
D) 5 = 11(0) + 5
5 = 5
